PNEUlVlATlC-DESPATCH TERMINAL.

SPECIFICATION forming part of Letters Patent No. 696,843, dated April 1, 1902. Application iled December 13, 1899. Serial No. 740,174. (No model.)

To all whom t may concern:

Be it known that I, ERBINE CURTIS PHIL- LIPS, a citizen of the United States of America, residing at London, England, have invented a certain new and useful Improvement in Pneumatic-Despatch Terminals, of which the following is a specification.

The object of this invention' is to improve the construction of pneumatic-despatch terminals. u

The terminal will be described when an exhaust in front of the carrier is used and such carrier is propelled by the ordinary air-pressure behind it, although it will be obvious that a direct pressure above atmospheric may be employed by suitably modifying the apparatus.

In the accompanying drawings, Figure 1 represent-s a substation-terminal, partly in section. Fig. 2 is a plan view on the line 1 l, and Fig. 3 is a diagrammatic view of a central and single substation.

The substation-terminals are made in two parts A and B, suitably curved and provided with iianges C C, by which they may be secured together at the desired angle. One part is connected to the incoming pipe D from the central station. The other part carries the outgoing pipe E, which either goes direct to the central station or connects with the ingoing pipe thereto. The outlet for the Acarrier at the substation is closed by a pivoted door or valve F, seating on an externallysurrounding rubber ring or like packing Gr and normally held closed by a spring H, but capable of being forced open by the carrier. The inlet for the carrier is closed by a like door or valve I, provided with a similar externally-surroundingA packing G and spring H. Inv both cases the arrangement is such that there is no wear on the packing due to the passage of the carrier. The dow oi' air or exhaust is from the central station to and through both parts A B of the terminal and back to the central station, as indicated by arrows and as will be clearly understood `by reference to Fig. 3, in which .I is the receiving-terminal of a central station from which the air is exhausted through K, the carriers to be despatched to substation L being placed in tube M, the terminal at substation L being of the form previously described, asis also the case when more than one substation is employed.

Vhat I claim is l. An upward-discharge terminal for pneumatic-despatch-tube systems, comprising in combination a substantially semicircular tubular member to be secured at one end to the upper end of the receiving-tube and constituting the discharging element of the terminala short straight tubular member adapted to be secured to the upper end of the sendingtube directly beneath and within the curve of said semicircular member and constituting the sending element of the terminal, and an air-return-pipe section uniting said curved and straight tubular members laterally near their discharging and receiving ends respectively, the space bounded by and included Within said parts being entirely open,whereby the sender is equally accessible from all sides of the terminal, substantially as described.

2. In an upward discharge terminal. for pneumatic-despatch-tube systems, a curved tubular member adapted tov be secured to the upper end of the receiving-tube and having its downwardly-discharging end closed by a door or flap, a short straight tubular member adapted to be secured to the upper end of the sending-tube and located directly beneath and within the curve of the said rst-named member and having its upper end closed by a suitable lid or door, and a pipe-section uniting said curved and straight tubular members laterally near their discharging and receiving ends respectively to permit the free circulation of the air-current through the terminal, all combined, substantially as set forth.

3. In a pneumatic-despatch apparatus, a terminal consisting of two members,means for holding said members together, an incomd ing tube attached to one member of said terminal, an outgoing tube in communication with the other member of said terminal and having its upper end open to the atmosphere, and valves for closing the outlet from said vterminal and the inlet to said outgoing tube.

4. In a pneumatic-despatch apparatus, a terminal consisting of two members, means for holding said members together, an incoming tube attached to one member of said terminal, an outgoing tube in communication With the other member of said terminal and having its upper end open to the atmosphere, and spring-controlled Valves adapted to automatically close the outlet from said terminal and the inlet to said outgoing tube.

5. In a pneumatic-despatch apparatus, a terminal consisting of tWo members, means for holding said members together, an incoming tube attached to one member of said terminal, an outgoing tube in communication with the other member of said terminal and located Within the curved members of the terminal and having its upper end open to the atmosphere, and valves for closing the outlet from said terminal andthe inlet to said outgoing tube.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
